First records of Xerocomus chrysonemus (Boletaceae) in the Czech Republic.

Abstract

The paper details the first collections of Xerocomus chrysonemus in the Czech Republic. The authors present a macro- and microscopic description of this species based on the study of material collected at five different localities. Characters distinguishing X. chrysonemus from related species of the genus Xerocomus s. str. (X. ferrugineus, X. subtomentosus, and X. silwoodensis) are discussed. The Latin name X. chrysonemus is a combination of the words ‘chryso’ = golden and ‘nema’ = mycelium, which very accurately describes the characteristic feature of this species, the golden yellow mycelium at the base of stipe.
